:cdokay I have some 6 weeks in with some older chicken everything is going good but in a few week the older ones will be eating layer food and the younger ones will still need grower will it hurt them if they eat the wrong food?
For a short time you could keep the older ones on grower feed and make sure they have free choice calcium. I think the calcium is the main difference between grower and layer. Then when they get close to 20 weeks they could all have the layer. Good Luck
